Why do I feel nauseous and want to vomit after drinking milk

Milk is a very common food in our daily life. Milk is rich in nutrients. Drinking milk regularly is very helpful to your health. For example, milk can promote growth and development, improve sleep, and supplement nutrition. Although milk is very good, there are many things you need to pay attention to when drinking milk. Some people feel nauseous and want to vomit when drinking milk. What's going on?

Why do I feel nauseous when drinking milk?

Pure milk contains a kind of sugar called lactose, which is slightly sweet and slightly fishy (it is this smell that makes you uncomfortable). Some people lack sufficient lactase to break down the lactose in milk, resulting in the inability of lactose to be broken down into glucose and galactose in the small intestine. In this way, lactose enters the large intestine without being fully digested in the small intestine, where it is fermented by a large number of bacteria to produce organic acids and gases. The acid and gas production causes a series of symptoms in the human body, such as intestinal rumbling, abdominal bloating, abdominal pain, diarrhea and even dizziness. This series of symptoms caused by poor lactose digestion and absorption is called lactose intolerance

People with lactose intolerance can use yogurt instead of fresh milk because the lactose in yogurt has been broken down, but it still retains the nutrients in milk.
